Imago. — Head very broad, not narrower than thorax, densely hairy, 
but without extra-antennal tufts; palpi with basal and middle joints 
much swollen (especially the middle joint, which is egg-shaped and 
twice as long as the basal one), and very densely clothed with scales 
and hairs (of which the marginal hairs on each side beneath are rather 
longer than the rest), — terminal joint long, not shorter than middle 
one, very slender, straight, not acuminate, clothed with exceedingly 
fine, short, closely-appressed hairs, porrected horizontally ; antennce of 
moderate length or rather short, very gradually and moderately thick- 
ened from about middle, and towards extremity tapering to a fine point, 
and very strongly recurved into a long hook. 
Thorax exceedingly stout, clothed with dense hair, longer than 
usual dorsally. Fore-wings more or less elongated apically ; costa 
nearly straight, but slightly curved at base and apex ; inner margin 
slightly concave ; discoidal cell narrow, long or very long (from three- 
fifths to two-thirds the length of w^ing), closed by slender disco-cellu- 
lar nervules in an inwardly-oblique line ; lower radial nervule well 
developed, originating midway between upper one and third median 
nervule ; first median nervule very long, much curved, given off not 
far from base at a great distance before origin of second. Hind-ivings 
more or less prominently and broadly lobate about anal angle ; basal 
protuberance of costa very prominent, fringed with hair ; disco-cellular 
nervules obsolete or reduced to an extremely attenuated line ; radial 
nervule also greatly reduced or obsolete. Legs rather long, stout ; all 
femora inferiorly, and middle and hind tibiae superiorly, more or less 
densely fringed with long silky hair; appendage to fore-tibise well 
developed ; terminal spurs of middle and hind tibiae, and second pair 
of spurs of the latter, rather long and stout ; all tarsi strongly and 
closely spinulose beneath. 
Abdomen thick, but tapering posteriorly, usually considerably 
shorter than inner margin of hind-wing, but in $ of some species 
almost as long ; a terminal tuft in ^.
